What Do Cabin Air Filters Do

Air quality is ofttimes disregarded when information technology comes to the air you actually breathe within your automobile. When it comes to cars and air quality, the starting time thing you think of is commonly going to exist related to vehicle emissions and the surround. Ultimately your vehicle's climate control system is one of the most of import systems in your car. You're afflicted by it virtually anytime you're behind the wheel. The quality of the air you lot breathe is important, especially as related to potential distractions and secondary health bug related to dust, mold, and other ecology contaminants. In this commodity, we encompass what exactly a cabin air filter does, how often to change the cabin air filter, and some of the best cabin air filters on the marketplace.

Despite this, the HVAC organization remains one of the most overlooked parts of a car when it comes to routine service and maintenance. In this commodity, nosotros'll review the nuts of how your AC system works, what a cabin filter is, and how it has evolved over the years, as well every bit some of the best ways you can maintain your car's climate command system for peak performance.

How does car air-conditioning work?

Simply similar the HVAC system in your house or apartment, the climate control system of your auto is designed to heat or cool the surroundings, and to provide fresh air to the passengers of the vehicle. Virtually every vehicle has two choices for rider airflow: fresh air or recirculated air.

Recirculated air means that the air already inside the motel is utilized equally the primary source of air for your HVAC system. This is particularly useful for the "max" setting for air workout, considering the air being used is already close to the desired temperature, making easier piece of work for the Air-conditioning organisation.

If your organisation is fix to fresh air, your vehicle's climate control system pulls fresh air from a vent under the hood. Typically this is located nearly the engine bay, either up in the pelting tray at the base of the windshield or otherwise separated by some sort of physical bulwark from the dirt, oil, and heat of the engine.

There are multiple benefits to this general location. One, the air intake vent is physically protected from the exterior air and debris. This position well-nigh the base of the windshield is also an area of high air force per unit area, which means that there is always a plentiful supply of fresh air for the organization to employ.

Once the air has entered through the air inlet, it is directed to the heater box. The heater box contains more or less all the major components of the climate control system, such as the blower motor, motel air filter, AC evaporator, heater core, flaps to select fresh or recycled air, too as flaps to divert air to dissimilar vents in the auto.

The cabin air filter does its thing starting time, removing physical particles from the air such as dirt, mold spores, and other particulate matter. At the same time, the activated charcoal section, if it's equipped with one, absorbs chemicals and other harmful or odor-causing contaminants.

From there, the air is sent through the blower motor, which dictates how much air is being pulled from the fresh air vent, besides every bit the strength of the air coming out of the vents inside the car. Ability going to the fan is controlled by the blower motor resistor, which is ordinarily located close to the fan to take reward of the airflow to keep the resistor from getting too hot.

Air then passes over a oestrus exchanger, the AC evaporator. If you have the Air-conditioning turned on or the arrangement is set to defrost, a refrigerant, typically R134A, has been compressed and supercooled by the compressor and condenser before beingness sent to the evaporator. Incoming air is cooled as information technology is forced over the evaporator core and equally it cools, moisture is removed from the air.

This drier air is more effective at keep the passenger compartment cool, as well as dissipating wet and condensation from the windshield and other interior surfaces.

If you've e'er wondered why there's often a puddle of water underneath your automobile in the summer, information technology's considering of the evaporator pulling moisture out of incoming air. All cars with an Air conditioning system have a drain that dumps the condensation from the air cooling procedure outside of the heater box, usually somewhere around the middle of the car.

If the climate command is set up to the heat setting, the air is forced across a second rut exchanger called the heater core. This works the same manner every bit an engine radiator, but with a different goal. With the engine radiator, ambience temperature air is used to cool the engine coolant being passed through the radiator in order to manage the heat generated by the engine.

The heater core uses the hot engine coolant to warm the air existence sent through it to warm upward the rider compartment.

After leaving the heater core or evaporator circuits, the air is and then directed by a final set of flaps to whatever interior vents are selected on the climate controls, such as the footwells, nuance vents, and defrosters.

A motel air filter is an integral role of all modern vehicle climate control systems. They're visually similar to engine air filters, and like engine air filters, cabin air filters are sized based on the volume of the air they are required to filter for efficient functioning.

What does a cabin air filter do?

A motel air filter'due south purpose is the same as any air filter in that information technology is designed to clean and filter air before some other component or element. The HVAC filter on a furnace or air conditioner at domicile is filtering air before it is taken into the organisation for either heating or cooling but is operating on a closed organization, and not really open to the outside air and elements.

A cabin air filter is working in the same capacity, filtering air before it is processed and introduced into the air ventilation organisation inside the car.  The difference is that the cabin air filter is dealing with potentially much more than harmful contaminants in the air since your car is often in the direct presence of dangerous air pollution.

These dangerous particles can include chemicals such as sulfur dioxides, nitrogen dioxide, and unburned hydrocarbons, as well as particulate matter from the exhausts of other cars and trucks. Exhaust from manufacturing or industrial output, as well general environmental particles like dirt, dust, and pollen are other contaminants that a cabin air filter is tasked with removing.

Who came up with cabin air filters?

The bones concept of a cabin air filter outset appeared dorsum in the 1950s. The chauffeur for erstwhile Freudenberg CEO Hans Freudenberg had noticed that his clothes were becoming noticeably dirty from the air coming in from exterior the vehicle. He had the original idea of placing a not-woven piece of fabric over the air vents to foreclose the excessive dirt from making its way into the passenger compartment. This unproblematic idea of placing a handkerchief over the top of an air vent was adult by Freudenberg into the modern cabin air filter that nosotros know today.

A cabin air filter is made out of pleated newspaper cloth, frequently with an activated carbon element. The pleated design increases the available filter surface surface area, and therefore air filtration capacity of the filter.  The activated carbon element absorbs contaminants and impurities via chemical absorption. This includes physically harmful elements, such every bit ozone, every bit well as the smell of fume or other unpleasant odors.

It was not until 1989 that a vehicle manufacturer incorporated this concept into a production vehicle. The 1989 Mercedes-Benz SL roadster was the kickoff vehicle to come standard with a cabin air filter from Freudenburg. Other college-end German marques such as BMW, Audi, and VW followed suit with optional cabin air filters on diverse models through their line-ups. The first mass-market place car to receive a cabin air filter equally standard was the 1991 Opel Astra, a European market meaty car, similar to the VW Golf or Jetta.

Throughout the 1990s, cabin air filters became more and more than common beyond multiple makes and models, but it wasn't until the early 2000s that nearly every car in the USA was delivered with 1 from the factory. Some cars during the menses were even manufactured with a location for a motel air filter but they weren't installed from the factory. If you own an older car from the late 90s or early on 2000s, you may be surprised if you check for a filter and find the spot empty. If and then, y'all can always add 1 now and experience the health benefits of a cabin air filter.

Volvo has taken this concept even farther with its Interior Air Quality System. The IAQS uses sensors to actively monitor the quality of air coming into the vehicle, and volition automatically close-off the outside air vent if it reads also high a level of carbon monoxide, nitrogen oxides, or hydrocarbons.

On the opposite end of the spectrum, manufacturers such as Mercedes, and Audi, are developing in-cabin fragrance engineering. These are literally systems that accept replaceable scent cartridges that let the commuter to cull a fragrance to be added into the motel air for a new individualized in-car air quality experience.

Freudenberg, as the developer and originator of the cabin air filter and supplier to many automotive OEMs, has continued to improve and innovate within the category. Through their micronAir make, a division of Corteco, itself a division of Freudenburg, they introduced the first charcoal activated combifilter in 1995. Continual updates in both filtering and activation mediums take resulted in the newest motel air filters existence able to remove even the smallest physical particles and irritants, filtering out particulates down to ≥two microns.

A micron, besides known equally a micrometer is a unit equal to i-thousandth of a millimeter, or one thousand nanometers. Here are some examples of different things of varying micron measurement to give y'all an thought of just how small ≥two microns really is.

• Skin cells 30 μm
• Crimson blood cells 8μm
• Pollen 90μm
• Flu .1μm (100 nanometers for reference)
• Staph 1μm
• Due east. Coli 2μm
• Web silk 5μm
• Human hair strand twenty-40μm
• Dust mites v-20μm

In 2019, 30 years later on the outset motel air filter was introduced, micronAir launched their Gas Shield activated carbon filters. These offer sophisticated activated carbon materials that are targeted and regionally customized for protection against extremely harmful air pollutants such as nitrogen, ammonia, ozone, aldehydes, and sulfur dioxides.  These latest Gas Shield motel air filters provide the maximum in anti-allergen, anti-viral, and anti-microbial protection.

What tin can you do to maintain your car's air conditioning system?

In that location are several simple things you lot can exercise to ensure your auto's climate control system is performing at its best. First, you should audit and replace your cabin air filter regularly. Secondly, if your motorcar is more than than a few years old, you may want to perform a deep clean of the evaporator and other system components. Lastly, you should make sure that your Ac system's refrigerant is up to spec and performing as it should.

How oftentimes to change a cabin air filter?

You should inspect and supplant your motel air filter annually, or well-nigh every 12,000 miles. Where you alive and the kind of environments in which you typically drive volition change this significantly. You should change your filter more ofttimes if you live in an area with extremely high humidity or an excessive amount of dust particulate, similar if you have a dirt driveway or spend a lot of time off-route.

How practise you know when to replace your motel air filter?

It is a fairly easy and straightforward procedure to inspect and supercede the cabin air filter in nigh vehicles. The cabin air filter is typically installed in the heater box which is under the dashboard typically well-nigh the firewall or the rider side footwell area. Some larger vehicles such every bit Audi A8, Mercedes S Grade, or BMW vii series may have 2 filters. Gaining access to the filter will depend on your vehicle, only it is usually fairly like shooting fish in a barrel and can be done with basic hand tools. We accept plenty of DIYs available for those looking to tackle these kinds of jobs at home.

Once y'all've removed the filter, give information technology a quick visual inspection for clay and debris. If your filter shows any signs of mold, a significant corporeality of dirt or a has an plainly soiled filter element, a rat's nest, or a mouse-business firm, it should exist replaced immediately. If the filter looks more or less brand new, gently open the external air side of the pleats to inspect the filter cloth. If everything looks make clean, you can reinstall the filter and check it again in a few months, or maybe at your next oil modify.  Keep in heed that just because the filer looks clean that doesn't always hateful that it's truly make clean and free of microscopic contaminants.

Does replacing your motel air filter matter?

Mostly, the performance of your vehicle's HVAC arrangement decreases dramatically without regular maintenance. The increasing pressure drop of air moving through a clogged filter might reduce the fresh air supply to the vehicles' passenger compartment, and cause the blower motor to work harder to overcome the restriction.

In terms of filtering efficiency, once the filter is clogged with debris, its power to capture smaller, and more probable more harmful to your health, particles are reduced. In the instance of an activated carbon filter, the capacity of the layer responsible for capturing harmful gasses and unpleasant odors tin can be reached, disabling the additional functionality of the filter. Once again just because it looks clean doesn't mean that it'due south even so working exactly as information technology should.

Ultimately, replacing your cabin air filter is something both inexpensive and easy to maintain on your machine. It also gives you peace of listen that yous and your passengers are receiving properly filtered air in a world constantly filled with boosted harmful pollutants.

How do you lot deep clean your AC organization?

Most professional person automotive repair shops have specialized equipment for deep-cleans of a vehicle'due south climate control system. These machines are typically large and expensive, merely an at-habitation solution is bachelor for DIYers. LIQUI MOLY has been at the forefront of developing these systems for 20 years, and offers an AC system cleaning kit that you can apply to practise it yourself at domicile.

With the LIQUI MOLY kit, a special ii-part cleaning solution is sprayed directly on the evaporator with a specialized spray gun, killing off mold and bacteria that may take accumulated over years of use. The best time to practice this is when yous're doing your annual cabin air filter replacement, saving you some time and the effort that it takes to access this part of the system.

The importance of keeping your Air-conditioning refrigerant charged

R134A is the life-blood of your car's air workout system. Information technology is what allows the arrangement to perform at its peak on the hottest days of the twelvemonth. Considering the system operates on a specific pressure level level, if your AC organization is low on refrigerant, information technology may not operate efficiently or even at all. Your AC components also rely on a lubricity that's added into the refrigerant accuse to keep switches and components operating smoothly.

R134A does have a bit of a shelf life, and so some refrigerant loss over time is not unusual. If your air conditioning isn't blowing cold and you've done the maintenance nosotros've mentioned above it may be time to seek professional person aid. Servicing the accuse on an AC organization requires special tools and a very specific process as far as evacuating and refilling the R134A level and pressure. This kind of refrigerant is nil you want you, or the environs, to be unnecessarily exposed to, so it'southward best to leave it to professionals with the correct tools and machines.

Hopefully, with this article, we've provided some insight into 1 of the more unremarkably disregarded but important systems of your machine. Performing just a few simple services such equally regularly inspecting and replacing your cabin air filter can go a long fashion to ensuring maximum functioning and the cleanest, most healthy air for you and your passengers when you drive your car.
